Summary of Multi salt experiments.
All experiments were performed with:
Flux 20 LMH (permeate flow 17 mL/min)
Crossflow of 0.5 m/s (feed flow 1160 mL/min)
The concentraiton of the various salts were selected based on concentration of authentic CT reservior water.
The pH was ajusted to pH 9.2 which is the lower end of the capacity for the bicarboante-carbonate buffer. The pressure was
The initial feed volume of 10.54 L, where 540 mL was taken out as samples. The experiment was set to run for 9 h and 5 min, bus as the feed tank ran out around 8 h 40 min, the experiment was stopped. This also mean there was no feed left when the experiment was ended. It was suspected that the feed thank ran out before time due to some water being “used”/supressed into the dampener, this volume was estimated to 250 mL. As the permeate flow is fluctuating this might also cause the faster time to use all feed water.

The average permeate flow was 16.995 mL/min, the plot show rooling average of the permeate flow indicating only minor flucturations during the experiment.
